Road 1 includes agitator tank 6, the peristaltic pump 7 being sequentially communicated, and described peristaltic pump 7 is connected with two Fluid sprayers 9 in spray tower 4, institute
Second fluid nozzle 10 is provided with two Fluid sprayers 9 stated, described air inlet pipeline 2 includes the air cleaner being sequentially communicated
11st, pressure fan 12, heater 13, hot-air distributor 15, described gas exhaust piping 3 include be sequentially communicated cyclone separator 17,
Air-introduced machine 18, sack cleaner 19.
Pressure gauge 8 is additionally provided between described peristaltic pump 7, two Fluid sprayers 9.
Wind pushing temperature meter 14 is additionally provided between described heater 13, hot-air distributor 15, at the air outlet of spray tower 4
It is provided with leaving air temp meter 16.
Described spray tower 4 is pressure mixed flow type atomizing drying tower.
The model BT300-2J of described peristaltic pump 7.
The course of work of the present invention, comprises the following steps：
Corronil powder is configured to slurries by I
By mass ratio be 4: 5 copper powder, nickel powder composition mixed-powder be well mixed with polyvinyl alcohol, deionized water, match somebody with somebody
Solid content is set to as 68% ~ 72% slurries, the mass percent of binding agent polyvinyl alcohol is 1% in slurries；
Slurries are placed in ball mill by II to be ground
Manufactured slurries in step I are placed on 2 ~ 3h of grinding in ball mill；
III running parameters are adjusted
Heater 13 in adjustment air inlet pipeline 2 makes wind pushing temperature meter 14 be maintained at 300 DEG C, will be compacted in feeding pipe 1
The speed of dynamic pump 7 is adjusted to 140 ~ 150rpm, so that pressure gauge 8 is maintained at 0.13 ~ 0.15MPa, adjusts in gas exhaust piping 3
